At the first signs of an allergic (hypersensitivity) reaction, stop taking Cetirizine 10 mg tablets and contact your doctor immediately. However, if cetirizine makes you vomit or have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. However, patients who experience somnolence should refrain from driving, engaging in potentially hazardous activities or operating machinery.

In addition to the adverse reactions reported during clinical studies and listed above, the following undesirable effects have been reported in post-marketing experience.

Take special care with Cetirizine 10 mg tablets if you have kidney problems, please ask your doctor for advice; if necessary, you may have to take a lower dose. If you are a hayfever sufferer, you may find taking the tablet throughout the hayfever season effective in keeping symptoms at bay. Allacan Cetirizine Hayfever Allergy Relief tablets contain the active ingredient cetirizine, a non-drowsy antihistamine that relives your symptoms of hayfever and allergy. In most respects, Cetirizine and Loratadine are similar, however, some people may find they respond better to one over another.

Both are non-drowsy antihistamines, they both come as a 10mg tablet, and both are once daily dosages. Renal impairment: There are no data to document the efficacy/safety ratio in patients with renal impairment.

The tablet formulation should not be used in children under 6 years of age as it does not allow the necessary dose adjustments.
